Re: [R] Obtaining and extracting cells sample in cross-tabulation
I don't know exactly what you mean, but perhaps this will get you started: This: subset(Data, X4==1 & X5==1, select=c(X1, X2, X3)) will extract the continuous variables in the cross-tabulation cell for which X4 and X5 are both equal to one. Similar commands will extract the other cells. Of course, this gets tedious if your categorical variables have more than two levels. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 6/17/16, 5:25 AM, "R-help on behalf of Gafar Matanmi Oyeyemi"wrote: >Hello everyone, >I'm writing a function in R but was stalked. >I have a data set that contains mixture of categorical and continuous >variables.

Re: [R] Obtaining and extracting cells sample in cross-tabulation
Your request is not clear. If you want to analyze the numeric variables by the groups formed by the categorical variables, try something like this. > # Create reproducible data > set.seed(42) > x <- data.frame(matrix(rnorm(75, 5), 25), X4=sample(0:1, 25, + replace=TRUE), X5=sample(0:1, 25, replace=TRUE)) > head(x) X1 X2 X3 X4 X5 1 6.370958 4.569531 5.321925 1 0 2 4.435302 4.742731 4.216161 0 1 3 5.363128 3.236837 6.575728 1 1 4 5.632863 5.460097 5.642899 0 1 5 5.404268 4.360005 5.089761 1 1 6 4.893875 5.455450 5.276551 1 1 > # Use split() to create a list of data frames > grps <- apply(x[, 4:5], 1, paste0, collapse="") > x.grps <- split(x[, 1:3], grps) > names(x.grps) [1] "00" "01" "10" "11" > x.grps[["00"]] # or x.grps[[1]] X1 X2 X3 8 4.905341 6.035104 5.089833 9 7.018424 4.391074 2.006910 14 4.721211 2.585792 6.399737 16 5.635950 5.205999 6.302543 18 2.343545 5.758163 6.038506 19 2.559533 4.273295 5.920729 20 6.320113 3.631719 5.720878 23 4.828083 6.444101 5.623518 - David L Carlson Department of Anthropology Texas A University College Station, TX 77840-4352 -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of PIKAL Petr Sent: Friday, June 17, 2016 9:24 AM To: Gafar Matanmi Oyeyemi; r-help@r-project.org Subject: Re: [R] Obtaining and extracting cells sample in cross-tabulation Hi did you try table or xtabs?

[R] Obtaining and extracting cells sample in cross-tabulation
Hello everyone, I'm writing a function in R but was stalked. I have a data set that contains mixture of categorical and continuous variables. I want to use the categorical variables to cross-tabulate the data and extract the observations in the resulting cells that contain only continuous variables. Data.
